And it is because they have so much to give and give it so lavishly to those who will wrestle with them that men love the mountains and go back to them again and again. The mountains reserve their choice gifts for those who stand upon their summits. (Sir Francis Younghusband)

Hi Bunuel,I have a question here,so when you considered both the statement and got x^3*y^4 = 5^3*2^4=2000.i want to know how you reached there? did you try plugging in x=1 ,2, 3 , 4 and 5 and y =1 , 2 etc?just trying to understand the thought process . when i tried to take both the statements i could not do that .
